A rose tinted campus life playing games with cute girls?
I'd call you a wishful thinker, but it's Hentai so it's quite possible. Also, the ass is complaining when his Osananajimi is there with him? At least he learnt to appreciate her company by that ending.
...So this time, the game was his wingman, huh. The right phrases just so happened to pop at the right time.

TiTiKEi is the first book by renowned hentai artist ISHiKEi (also known under his circle name as Nise Midi Doronokai). It is a compilation of all of his original work since the first chapter, "Various Lewd Things" (Insei Iro Iro), debuted in COMIC Masyo back in 2005. TiTiKEi was the best-selling hentai manga in 2013, breaking records in Japan and solidifying ISHiKEi as one of the top hentai artists in the world.
